1. A sample variance is computed in the same manner as a population variance.

2. If a population has a mean of 10 and a standard deviation of 2, then the sampling distribution of averages of samples of size n = 2 has a mean of 10 and a standard deviation of 1.

3. The variance of a sampling distribution of averages is larger than the variance of the underlying population because y has more distinct values than y.
